GLib.unix_open_pipe

function unix_open_pipe(fds: Number(gint), flags: Number(gint)): Boolean {
    // Gjs wrapper for g_unix_open_pipe()
}

Similar to the UNIX pipe() call, but on modern systems like Linux uses the pipe2() system call, which atomically creates a pipe with the configured flags. The only supported flag currently is %FD_CLOEXEC. If for example you want to configure %O_NONBLOCK, that must still be done separately with fcntl().

This function does not take %O_CLOEXEC, it takes %FD_CLOEXEC as if for fcntl(); these are different on Linux/glibc.

Since 2.30

fds: Array of two integers
flags: Bitfield of file descriptor flags, as for fcntl()
Returns: true on success, false if not (and errno will be set).
